System: 304 stainless steel construction provides lasting protection for water heaters by effectively removing sediment, rust, and debris from the incoming water supply to maintain heating efficiency and extend appliance lifespan. Sediment Removal Technology: Advanced PP cotton and stainless steel mesh combination captures particles down to fine levels, preventing mineral buildup and scale formation that can damage water heater elements and reduce heating capacity. Compact Design: Measuring 125 x 83 mm, this prefilter fits standard water heater inlet connections; installation is straightforward without requiring additional plumbing modifications for most households. RustResistant Materials: Constructed with 304grade stainless steel components that withstand water pressure and temperature fluctuations, maintaining effectiveness while resisting erosion and maintaining integrity. Use scenarios: Use in homes with hard water or sediment to protect the water heater and extend its life. Use when maintaining or replacing a water heater in areas with older pipes or mineralrich supply to reduce debris entering the tank. Use in DIY installations where minimal plumbing changes are preferred, as the unit fits standard inlet connections.
